44 Claims.

- This invention relates toa machine for pouncing or finishing hat bodies.

One of the objects of this invention is to provide a machine for finishing hat bodies which is simple in construction, efficient in operation, and sturdy and durable under conditions of rigorous use. Another object is to provide a machine of the above nature which is largely automatic in operation and does not necessitate the attention of skilled labor. Another object is to provide a machine of the above nature capable of imparting a smooth velvety finish to a hat without the production of any tool marks thereon. Other objects will be in part apparent and in part pointed out hereafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings in which are shown several embodiments of my invention,

Figure 8 is an enlarged fragmentary sectional elevation of the hat block supporting and operating head of the machine shown in Figure 6. This view also is illustrative of a modification of the machine shown in Figure 6.

"Similar reference characters refer to similar parts throughout the various views of the drawmgs.

In general, and with reference to Figure 1, my

' pouncing machine comprises a column generally indicated at-IB, formed by a base H, a motor housing l2, an extension l3 and a head I4. Preferably these parts are separate castings which may be secured together in any suitable manner.

A shaft i5 is journaled in head l4 and has secured on one. end thereofla chuck it which tool assembly 28 is also carries a hat block H on which a hat body I8 may be mounted. On the other end of shaft I5 is a driven pulley 19 connected by a belt 28 to a driving pulley 2|, associatedwith a clutch generally indicated at 22. Clutch 22 is driven by a motor 23 mounted in housing [2 and thus shaft 15 may be driven to rotate hat block l1. Motor 23 also-drives an oil pump 24 by means of pulleys 25 and 26 connected by a belt 21. Preferably pump 24 is mounted in the upper part of base ll of column l0.

A pouncing tool assembly generally indicated at 28 is rotatably mounted on a bracket generally indicated at 29 and extending from base H, this assembly being movable about and toward and away from hat block I! through instrumentalities to be described hereinafter. Pouncing too1 assembly 28 includes a pouncing tool generally indicated at 30 and driving mechanism therefor as will be described in detail hereinafter.

Oil pump 24 supplies oil under pressure to hydraulic mechanism disposed in and on base H, and partially housed within a' casing 3|. For a detailed description of this hydraulic mechanism and its operation, reference is made to my United States Patent No. 2,137,250.

The hydraulic mechanism includes a piston (not shown) connected to a rack the end of which is shown at 32 (Figure 1) and this rack meshes with a gear or train of gears (not shown) as desirable to rotate a heavy stud 33 to which a bracket 34 is secured.

Tool assembly 28 s connected to bracket 34 andaccordingly upon operation of the hydraulic mechanism which effects rotation of hollow stud 33 (see also Figure 5) pouncing tool assembly 28 is moved about hat block 11 in a substantially circular path. The above-described driving conhydraulic mechanism and particularly described in my above-noted copending application.

Referring now to Figure 5, bracket 34 is rotatably mountedon'bracket 29 by ananti-friction bearing 35, and the free end of bracket 34 has secured thereto a pair of springs 36 which have connected thereto a tool assembly supporting bracket 31. Bracket 31 has secured therein a stud 38 on the ends of which is rotatably mounted a supporting plate 39. Stud 38 also carries a casing 48 which houses a spring (not shown) the tension of which is adjustable by knob 4!. This spring is suitably connected to tool assembly 28 (Figure I) and its tension is adjustable by knob Al to bias tool assembly 28 toward hat block I] nections between the at various desired pressures, all as is described in detail in my above-noted Patent No. 2,137,250.

Referring back to Figure 5, supporting bracket 39 includes a generally ovate slot 42 (see also Figure 4) which adjustably receives the tubular portion 43 of a support generally indicated at 44. Support 44 includes an integral plate 45 provided with slots 45 (see also Figure 4) which receive machine bolts 4! adapted to be threaded into supporting plate 39 to secure support 44 thereto. Support 44 also includes upper and lower shoulders 48 and 49 (Figure respectively, in which anti-friction bearings 58 and 5| are set. These bearings rotatably carry the tubular extension 52 of a plate 53, extension 52 being disposed within tubular portion 43 of support 5 and held therein by a collar 54. Plate 53 also has a pair of slots one of which is shown at 55 through which machine bolts 58 are adapted to extend for a purpose to be described hereinafter.

With, reference to Figure 1, tool assembly 28 comprises a motor housing 51, a crank case 58, a casing 59 and a housing 68. Preferably these various portions of tool assembly 28 are separately cast or fabricated and are bolted or screwed together in any desirable fashion. If desired, housing 58 may be connected to casing 59 by a driven fit. Motor housing 57 includes a base 8i which, with reference to Figure 5, rests on the machined top of plate 53. Bolts 55 are threaded into motor housing base 6!, and as these bolts extend through slots 55, the motor base is adjustable along plate 53. Thus tool assembly 28 is adjustably connected to plate 53 which, through its variable connection with support 53, is adjustable or movable with respect to supporting plate 39, i. e. the tool assembly as a unit is pivotable about the axis of extension 52 of plate 53. Hence, what will hereinafter be termed the swivel aXis of the tool is adjustable toward and away from what will hereinafter be termed the swinging axis of the tool (the axis of stud 38) by virtue of the adjustable connection afforded by bolts 41 which extend through slots 48 into supporting plate 39. The purpose of the adjustments afforded by support 44 and plate 53 will be described below.

With reference to Figure 1, motor housing 51 is adapted to receive a motor 52 which is adjustably held within the housing by a strap (not shown) which may be taken up by a nut 63 to hold the motor in its set position. Motor 62 is connected by means of pulleys 64 and 65 and belt 66 to the mechanism in crank case 58.

As is more clearly shown in Figure 2, crank case 58 has suitably set therein a pair of antifriction bearings 81 and 68 which rotatably carry a shaft 89, the outer end of which is borne by an anti-friction bearing 18 set in an extension H bolted to the side of crank case 58, and it is on this shaft 89 that the driven pulley is mounted. Shaft 69, which in fact is the crank shaft, includes throws or eccentrics l2, l3 and 14, about which are respectively mounted anti-friction bearings 75, I6 and TI. Bearing 18 carries a connecting rod 78 to which is bolted an operating rod I9 or the like, this rod preferably being formed of an extremely light but strong alloy, such as Dow metal. The upper portion 79a of rod 19 is preferably sprayed with steel or a suitable alloy thereof and ground to provide a bearing surface capable of reciprocating in a bushed guide 88, whose upper integral end 8| has extending trunnions 82 and 83 journaled in suitable bushings 84 and 85 mounted in housing 88. The upper end of housing 60 has an annular shoulder to carry a flanged cap 81 Whose sides 88 extend downwardly about and around housing 68 and the ends of trunnions 82 and 83. It will now be clear that upon rotation of crank shaft 69, connecting rod 18 and accordingly operating rods 18 are reciprocated along the axis of the rods and rocked about the axis of trunnions 82 and 83.

As shown in Figure 1, pouncing tool 38 is connected in any suitable manner to the top of rod 19 and accordingly partakes of the movement of the rod; thus the tool travels in a substantially elliptical path. It should also be noted as pointed out above, that the tool is capable of traversing hat I 8 in a path extending from the crown to the brim, i. e. in a path substantially conforming to the contour of hat block l1. Furthermore, the tool is movable toward and away from the head about its swinging axis through the coaction of a cam 280 and roller 28l as described in detail in my above-noted copending application. It should also be noted that tool 30 is freely movable with relation to the head about its swivel axis described above.

While mechanism has heretofore been provided for driving a pouncing tool through an elliptical path as for example the mechanism disclosed by Casse in his United States Patent No. 2,006,260, there are many advantages to be derived from completely dampening vibration resulting from the pure rectilinear reciprocation of the tool and for counteracting the rocking forces resulting from movement of the too through its elliptical path while at the same time providing a freely swiveling tool which is not positively constrained to any definite position with respect to its swivel axis. To this end I have provided a pair of sliding shoes 89' and 98 whose lower ends encircle and accordingly are carried and driven through anti-friction bearings 15 and 71 by crank shaft 55. As these shoes are substantially the same, only one will be described in detail. Thus shoe 89 (Figure 3) is cored out to provide a runway EH which embraces the sides of a rocking guide 82 having formed thereon a hollow boss 93 (Figure 2). This boss is mounted on a stud 94 the outer disc-like end 95 of which is disposed between the outer end of boss 93 and the inside surface of a plate 96, which is bolted to housing 59 by bolts 91. Similarly sliding shoe is provided with a rocking guide 98 pivoted on a stud 88 held in place in housing 55 by a plate I00 bolted thereto; Preferably the lower ends of rockers 92 and 98 are cored out while the ,upper shaft throws 72 and 13 with respect to throw 14, sliding shoes 89 and 98 reciprocate oppositely to the reciprocation of connecting rod 18 and rod 79.

It will now appear that in view of the abovedescribed counter-balancing features, and in view of the resilient mounting of tool assembly 28 on bolted to motor housing 6I I01 carrying an, operating knob I08 As hereinbefore noted, tool assembly 28. (Fig-- freely pivotable e., the axis of me 1) and accordingly tool 30 is about the tools swivel axis, i. plate extension 52 (Figure circumstances, it might be desirable to move this swivel axis toward or away ing bolts 41 and moving support 44 relative to supporting plate 39. This variation in the swivel axis however, would' move the pouncing tool too far from or too close to the hat. Accordingly a compensating adjustment is made by unloosening Under certainv from the hat block,. and this may readily be accomplished by loosenthrough the. systemoflevers A (Figure 1) as described in;my above-noted Patent No. 2,137,250. Byivirtue of. the. 'ca11y:moving pouncing tool 30, a hat of any contour, Le a hat having a sharp or rounded square, may be given a soft, velvet-like finish free from any .tool marks. I Pouncing tool 30. also includesmechanism for automatically feeding .iabrasive paper over the pad substantially as'described in" detail in my above-referred to .copending application. I v i I While the above-described machine is par-- ticularly well adapted to pouncing blocked hats, it is-necessary to pounce unblocked hats, particularly hat bodies .being' prepared for the manufacture of womens hats. Such hat bodies often have no definite head size, and often are quite deep and generally conical in shape. Hat bodies difficulties encountered in.

bolts 56 and'thence moving motor housing base 6I over plate 53' by an amount equal to the adjustment between support 42 and supporting plate 39. If after this adjustment itis'found that the tool assembly has become unbalanced (it being desirable that assembly 28 be in substantially perfect balance in order that the tool may freely pivot about may be moved to the right or left in its housing 51 to bring the assembly back into balance.

While the 'above-descr'bed adjustment may notoften be necessary, reason of a hat block of different contour or depth being used. Thus for a hat block wherein the square is quite sharp and pronounced, one adjustment may be necessary which is quite different from the swivel point setting desirable for aghat block withia rounded square.

Furthermore, in connection with hat blocks of varying depth, I'have provided (as shown in Figure 4) a bent plate I04, one end of which is and the other of which is adapted to enter a notch I05 formed in an eccentric I06 mounted on a rotatable shaft at one end, and an indicating disc I09 at the other. Preferably disc I09 is graduatediaccording to different hat block depths and registers with .a suitable indicator so that the operator of the machine may immediately set the disc at the desired indication. Turning of knob eccentric I06 and raises or to adjust tool assembly 28 about its swinging axis, i. e. axisof stud 38; so thatthe tool is cor.. rectly presented to the tip of.the hat on the block; Engagementof plate I04 in notch. I05 serves a further purposein preventing the motor housing 6|, the crank case and pouncing tool assembly, from swiveling while the wholeunit islifted out of engagementwith the hat body.

. The pressure with whichqthe tool is forced against the hat is controlled in substantially the that described in my above-re-.

same manner as ferred-to patent:No.-2,13'7,250. Thus, referring torFigure "4, aleafspring I I0, the tension of which may: be adjusted, biases the tool assembly.

its swivel axis) motor 62 (Figure 1) it occasionally is so by I08 accordingly rotates lowers bent plate I04:

' of .this nature accordingly preclude the mounting thereof onhat blocks such as hat block H in Figure 1, i. e. hat-blocks turnedto a definite head. sizeffor.conformation.v Therefore, to obviate the hand pouncing such hat/bodies, thepouncing machine shown in Figure 6 is directed. In general organization,

this machine'isfsimilarto that shown in Figure 1,

and accordinglyincludescolumn I0 comprising base II, a motor housing I2. and extension. I3;

However, a special head generally. indicated'at III is mounted. on extension I3 and. this head rotatably mounts a spindle II2 driven by. motor 23.through pulleys H3, H4 and belt II5. As is more clearly shown in Figure 8, spindle H2 is ably mounted for rotation and also axial movement. within ajournal. Ila, the spindle having [and its operating mechanism,

associated therewith clutch mechanism generally. indicated at ll8whichlis.operated by engaging and disengaging apparatus generally indicated at II9. For a detailed description of the details of.

construction and operation of the spindle clutch reference is made to my U. S. Patent No. 2,105,130.

The left-hand end of spindle. II2, as viewed in Figure 8, has secured thereto a back support generally indicated at portion I2I, which carries anti-friction bearings I22 and spindle II2 is'rotatably mounted. The: lower end ofbacksupport I20 has a boss I24in which is secured an end 'I25a of a rod I25, to the other endiof'which a piston I26 is attached. Piston I26 is adapted to reciprocate in a cylinder I21 secured to head III, as oil under pressure is fed into one end or the other ofthe cylinder, as particularly described in my f'a'bove-noted U. S. Patent No." is "actuated, as noted 2,105,130. Whenpiston I26 in my patent, spindle H2, and accordingly sup; port. I20,*are moved axially and this for a purpose to be described.

The extreme and II2-b of spindle H2 is further reduced and has secured thereto so as to rotate therewith a spider I28. The right-hand end of spider I28, as viewed in Figure 8, is formed toa block I30 as by screws I3I, block I30 having a generally frusto-conical shape. The outer surface of the block is covered prefer'ablywith a Back support I20 k. The machine asshownfinFigureiLis operated.

piece of felt I32 or the like. at its larger end'l20a is annular and has attached thereto a hood I33'by bolts I34.

As is-more clearly shown in Figure .6, hood I33 has an enlarged slot I35 formed therein and extending from near the .thetip or rounded end of balanced free swiveling. ellipti- I20 having a tubular hub I23 in which areduced end 211. of;

in an annulusor ring I29 and has secured there base of the hood over the hoodj'so as to ex-n pose a substantial portionof felt covered block I; Hood I 33-is so mounted that slotv I35 is arranged in registry with pouncing tool :30 so that when the 'tool' traverses a hat body mounted on' the hood, it travels in apath extendingfrom the tip. ofthe hat toward. the: brim thereof. As notedabove, however; the hat body is. often of substantial depth, and accordingly extends fare. ther over hood I33 than the limit of traverse of thentool therealong. It is for this reason that axial movement of hat block spindle I I2 and the parts attached thereto are axially movable. Thus, as described in my U. S. Patent No. 2,105, 130, after the tool has reached the extent of its travel, the spindle, and accordingly hoodi1I33. is automatically actuated "to move. the hat body pastthe tool as thetool continuesv to operate until all. portions of the hat have been pounced, and thereafter reverse the movement of the hat back to the point where reversal of the movement of thetool is automatically begun- In view of the fact that hat bodies pounced. on the machine just described vary substantially in head size, I have provided means for holding thehat in a position where the tool can operate on it and also for feeding thehat past the elliptically moving tool. Thisholding and feed-. ing mechanism, as shown .in FiguresG and 7, comprises a system of pipingl3ii connected to a. suitable source of compressed air, and connected at its upper end to a'header I3! from which a pair of pipes I38 and I39 lead respectively to Ts I40 and I-II. ,Each of these Ts has connected: thereto a pair of pipes I42 and I43 which terminate .in nozzles or jets I44 and I45, respectively, at the bottom, and top edges of pouncing pad 30a and adjacent the operative surface thereof. As is best shown in Figure '7 nozzles I44 and. I45 areso directed that blasts of air issuing there-v from impinge against a. hat I46 mounted on hood I 33 at points respectively adjacent the lower and upper edges of hood slot I35. from jets I34 and I35 is .of sufficient pressure to blow hat I46 firmly enough against felt covered block I30 so that the hatadheres thereto. as. the block rotates. Thus hat I46 is rotated, for example, in the direction, of: the arrow, and as its. lower portion I43a moves 'overthe bottom edge of slot I35, the air. pressure from nozzles I44 forces it against felt covered block I30. 'Simi-' larly, as upper portion I43b of the. hat moves; against the upper edge of slot I35,, the hat is peeled from the hat block so as to ride over the outer surface of hood I33. Hence, it. may be seen that that part of the hat between portions. MM, and I461) thereof is held against the rotating hatblock in a position where it may be worked on. by pouncing tool 30.

If for any reason the hat body I45 is not of sufficient depth to completely cover. slot I35 shown in Figure 6, a suitable shutter or the like (not shown) may be provided for hood I33 to cover that portion of slot I35 not covered by the hat body. Air pipes I36 maybe connected in any suitable manner totool assembly 28 and have any type of suitable and socket joints or flexible tubing, which will not interfere with the free swiveling of the tool assembly. Furthermore, by the provision of the symmetrically placed nozzles I44 and I45, i. e. symmetrical with respect to 'pouncing. pad 30:1,. the air pressure against the hat. on each side of the pouncing pad is substantially equal and accordingly tends to keep the pad in proper tangential position with respect to thev hat block without, however, adversely affecting free swivcling of the pouncing tool.

Under certain circumstances, it may be desirable to hold the 'hat body against hood I33 by negative pressure instead of positive pressure. In view of the fact that the only opening in hood I33.is. that provided by slot I35, a partial vacuum can be maintained within the hood when a hat body is placed. thereover so as to cover the slot. This partial vacuum has the same effect in holding a hat body against block. I30 as does the positive pressure exerted by the jets directed against the outer surface of the hat body. Hence, with reference to Figure 8, I have provided a pipe fitting 'I4'I registering with an opening I48 in back support I20. Anysuitable piping (not shown) may be connected to fitting I4'Iand with any. suitable evacuating system. If desired, a pump (notshown) may be disposed within column extension I3 or elsewhere in .or on the machine and pneumatically connected with fitting I41 and accordingly with the inside of hood I33. It follows, that upon operation of such a pump, air is sucked from within the hood, and a hat disposed thereon is pulled against block l30'so as to rotate therewith ashereinbefore described.

Accordingly I have provided a pouncing machine which accomplishes the various objects hereinbefore set forth in a thoroughly practical and eilicient manner.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth, or shown in the accompanying drawings, is to be interpreted as'illustrative and not in a limiting sense.
